WIRE-CLOTH RACK.

Application filed March 1 To all w/iom t may concern:

Be it known that I, ANTRUM W. JOHN- soN, a citizen of the United States, residing at TWarrenton, in the county of lVarren and State of Missouri, have invented certain new and useful Improvements in VVire-Cloth Racks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will `enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a wire cloth rack and has for its primary object to provide means for accurately measuring wire cloth when unwound from the rack.

An object of this invention is to provide a pair of upwardly and inwardly inclined supporting bars, having a plurality of notches to receive the ends of spindles, which support rolls of wire cloth, whereby various widths of rolls of wire cloth may be accommodated and efficiently supported by the supporting bars.

Another object of this invention is to provide a measuring roller, having a friction roller adjacent thereto, to receive the wire cloth as it is unwound, to measure the wire cloth in desired lengths.

A further object of this invention is to provide meansfor raising and lowering the measuring and friction rollers to place them in parallel alinement with any one of the rolls of wire cloth which is being unwound.

A further object of this invention is to provide means for locking the measuring and friction rollers in parallel alinement with any one of the rolls of wire clot-h. A still further object of this invention is the provision of a wire cloth rack of the above stated character, which will be simple, and efficient, and which may ybe manufactured and sold at a comparatively low cost.

With these and other objects iii view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement'of par-ts as will be hereinafter more fully described and For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which r- Figure 1 is a front elevation of a wire Specification of Letters Patent.

0 Fig. 6 is a fragmentary longitudinal sectional view taken on the line ko of Fig. 1, and

Fig. 7 is a perspective view of a collar for loclgiiig the measuring roller in a desired position.

Referringin detail to the drawings, the numeral 1 indicates a pair of transversely extending feet, having upwardly and inwardly extending' supporting bars 2 secured thereto, which are provided with a plurality of upwardly directed notches 3, to receive spindles 1l, having rolls of wire cloth 5 thereon. Any number of spindles 4 of various lengths may be supported upon the supporting bars 2 for supporting rolls of wire cloth of various widths. The upper ends of the supporting bars 2 are secured together by a its ends projecting to points beyond.

A pair of vertically extending rack bars are secured to the feet 1 and to the ends of the cross beam 6 and provided with rack apertured to receive a shaft 10, having collars 11 thereon to prevent lateral movement thereof. Secured to the shaft 10 is a fricthat rotates with the shaft 10 and which will be hereinafter more fully described. The shoes 9 are provided with openings 13 to receive a shaft 15. The shaft 15 has secured thereon a measuring roller 16 which is 12 inches in circumference and positioned in parallel alinement with thefriction roller 12. Journaled upon the shaft l5 are pinions 1'?n shoes 9 and provided with oppositely disposed slots 18. The pinions 17 are in mesh with the rack teeth 8 and adapted to move upwardly and downwardly thereon, causing the shoes 9 to move upwardly and downand positioned within the wardly on the rack bars 7, carrying the friction roller 12 and the measuring roller 16 therewith.

Keyed to the shaft 15 are collars 19, having arms 2O formed thereon and are adapted to extend through the openings ,13 in the shoes 9 and engage the slots 18 in the pinions 17, when the shaft 15 is moved laterally on the rack bars 7 to lock the rpinions 17 to the shaft 15. Secured to one end of the shaft 15 is a crank handle 21 and by rotating the shaft 15 by the crank handle 21, the pinions 17 are caused to travel upwardly or downwardly on the rack barsA 7 depending in which direction the shaft 15 is rotated to move the friction roller 12 and measuring roller 16 in parallel alinement withv any one f of the rolls of wire cloth 5.

To loci; the friction roller 12 and measuring roller 16 in parallel alinement with any one of the desired rolls of wire cloth r5, the

shaft 15 is provided with collars 22, havingy arms 22, similar to the arms 20. The col- V.lars are apertured to receive pins 23 that extend into grooves shaft 15 in a lateral direction and opposite to the/heretofore mentioned direction, the arms 22 will pass through vertically eX- tending slots in the shoes and engage the slots 18 in the pinions 17 and prevent the pinions from rotating, thus holding the shoes 9 stationary upon the rack bars 7.

1n operation the rolls of wire cloth 5 are positioned upon the supporting b`ars2 and arranged thereon according to the width of the various rolls of wire cloth. The operator desiring to unwind and measure simultaneously the wire cloth from a certain roll, the handle 21 is pulled in a lateral direction or in the direction of the operator, causing the arms 20 on the collars 19 to engage the slotsV 18 of the pinions 17 and by turning the crank handle 21 in a desired direction, the pinions willr be unwound and measured. After the measuring roller 16 and the friction yroller 12 are in parallel alinement withthe desired roll of wire cloth, the shaft 15 is shoved in a reverse lateral direction causing the arms and the collars 22 to pass through the vertically extendingy slots of the shoes and engage the slots 18 of the pinions 17 and disengaging the arms 20 of the collars 19 therefrom, thus lockingl the pinions 17 against rotation and holding the shoes 9 stationary upon the rack bars 7. The yend Vof the wire cloth is threaded between the measuring roller 16 and the friction roller 12 and by rotating the crank handle 21, the measuring roller will rotate rand unwind the wire cloth and upon every complete rotation of the measuring roller, a foot of wire cloth will be unwound. The shaft 15 is free to rotate within the shoes 9, 'pinions 17 and the col- 24 and'by moving the be forced to travel in the n v` direction of the roll of wire cloth which is to lars 22, as the pins 23 engage the grooves 24 permitting free rotation thereof.

A scale of 12 inches isapplied to one end of the measuring roller 16, to indicate that upon one complete revolution of the measuring roller 16, a foot of wire cloth has been unwound.

While l have shown and described the ypreferred embodiment of my invention, 1t

that minor changes in will be .understood construction, combination and arrangement of parts maybe made without departing from the spirit and scope of the invention as claimed.
